1. Solar Energy and a Changing the
World

2. The popularity of solar energy has always been tied to the viability of its
competing energy sources. Every oil embargo or energy crisis sees the
popularity of solar rise, and then fade when the supply of cheaper fossil
fuels returns to normal. This is a trend that looks to be ending soon.
Bloomberg New Energy Finance (BNEF), responsible for some of the most
advanced new energy estimations in the world, has stated that the cost of
solar power has dropped by around 33% in emerging markets since 2010.
Not only does this mean that solar has now beaten wind as the least
expensive form of renewable energy in developing parts of the world, but it
means it has also begun to beat out coal and gas in some instances as
well. Private solar companies bidding on development in India and Chile
came in at only half the cost of coal.

3. Once we enter the world of renewable energy being able to undercut the
prices of fossil fuels regularly, our world will begin to look a lot different.
The fact that new solar projects have become more efficient to build than
wind turbines, and even some fossil fuels, has a lot to do with the
development of cheaper equipment and more efficient processes. These
innovations come after China, and a series of emerging economies like
India, Pakistan, and Egypt have made a concerted effort to develop
renewable energy sources. China alone is set to install over 110 mln KW of
solar power by 2020.

4. While subsidies continue to play favorites in large economies like the United
States and Australia, the innovation driven by the developing world has
begun to seep into commercial solar systems and home solar systems
everywhere. Even in the U.S. solar energy prices dropped around 12% in
the last year, fitting the trend we have seen ongoing since 1977 (the cost of
solar panels in 2013 was around 100 times cheaper than the cost of solar
panels in 1977.) Oxford University predicts a continuing drop in costs
around 10% a year.

5. Commercial solar systems, home solar systems, and photovoltaic power
plants will be able to outperform the traditional alternatives effectively.
Unlike wind power, solar is a viable choice for individual's homes, and
homeowners will continue to jump at the money saving opportunity in
increasing numbers. In Australia, a 5.7kw system typically saves
homeowners over $1,200 from their power bill in the first year. As more
efficient systems can do the same in traditionally less sunny locales, we
may very well see a fundamental change in many economies and how their
energy Industries are ran. Solar is on track to easily disrupt wholesale
energy prices, and that will force countries to redesign their utilities and
budgets around a more empowered populace.
